NUT-LOCK.

Specification of Letters Patent.

Patented NOV. 9, 1915.

Application filed. OctoberS, 1913, Serial No. 794,251. Renewed July 24,1915. Serial No. 41,800.

To all whom it may Concern:

Be it known that I, EDWIN R. TALLEY, a citizen of the United States,residing at Algona, in the county of Kossuth and State of Iowa, haveinvented certain new and use ful Improvements in Nut-Locks, of which thefollowing is a specification.

This invention relates to new and useful improvements in nut locks, andthe primary object is to provide a device of this character which willpositively lock a nut in place to prevent casual disengagement thereofin use. r

A further object of the invention resides in providing a key on the nutadapted for engagement with a slot in the bolt, and a still furtherobject resides in providing an improved means in connection with the nutfor retaining the key out of view when same is effectively disposed.

Still another object of the invention is to provide a device which issimple and durable in construction, inexpensive to manu facture and onewhich is very efi icient and useful in operation.

lVith these and other objects in view, my invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification and claims.

In the accompanying drawing forming a part of this application:

Figure 1 is a perspective view of a device embodying my improvements.Fig. 2 is a vertical section therethrough, partly in elevation. Fig. 3is a perspective view of a nut embodying my improvements and disclosingparts separated. Fig. 4 is a horizontal section through the deviceapplied.

In describing the invention I shall refer to the drawing, in whichsimilar reference characters designate corresponding parts throughoutthe several views, and in which 1 indicates a bolt of the usual or anypre-' ferred type having the longitudinal slots 2 in the threadedportion thereof at diametri' cally opposite points thereon. Adapted forengagement with the threaded port-ion of the bolt is a nut 3 ofhexagonal or other de sign, one face of whichhas a portion or stripremoved therefrom to form a separable plate 4. This plate, it will beunderstood, when applied to the referred-to face of the nut, willcomplete the formation of the latter.

Extending through the nut from the face having the strip removedtherefrom tov the bore ofthe same is a threaded channel 5 with which isengaged a screw or threaded key 6. The outer end of the channel 5 ischamfered so as to receive the head of the screw 6 in countersunkrelation therein, and when the head is so positioned the end of thescrew is adapted to be received in one of the slots 2 of the bolt. Fromthis construction it will be seen that after the nut has been properlyturned home on the bolt the same is positioned to permit the channel 5to register with a slot 2 in the bolt. The screw may then be introducedthrough the nut to obviously lock the latter in its eifective positionon the bolt.

In order to prevent the casual disengagement of the screw 6 and also tohide the same from view, I provide a means for re movably supporting theremoved plate or strip 4 in position on the face of the nut from whichsame is removed. To this end the last referred to face of the nut isprovided with a threaded opening 7 adjacent one corner thereof and theplate 4: is provided with an opening 8 adapted to register with theopening 7 when the plate is properly applied on the nut. An additionalscrew 9 is adapted for introduction through the opening 8 to be engagedwith the threaded opening 7 whereby to pivotally support the plate a onthe nut. In order to limit the swinging movement of the plate on the nutin one direction, the one face of the nut is provided with a cavity 10,the inner wall of which is beveled, while the inner face of the plate 4.is provided with a projection or lug 11 adapted to be received in saidcavity. The one end of the projection, contacting with the one wall ofthe cavity, obviously limits the swinging movement of the plate 4,retaining the latter in such position as to complete the formation ofthe nut proper. When it is desired to disengage the nut, the plate amust first be raised or swung on its pivot, so that engagement may behad with the screw 6 whereby to disengage the latter from the bolt. Thenut may be removed as usual. I

From the foregoing description of the construction of my improved devicethe operation thereof will bereadily understood,

and it will be seen that I have pr vided a device which: is simple anddurable in construction, inexpensive to manufacture and one which willbe very efiicient and useful in operation.

W hat I claim is:

1. The combination with a bolt having a longitudinal slot in thethreaded portion thereof; of a nut having a transverse opening therein,a member insertedinthe trans verse opening of a nut for engagement Withthe slot in the bolt-to loek tlie'forin'eron the latter and a platepiy'oted to one face of said nut to conceal said member, said platecovering the entire face of the nut.

The cornbination: with" a bolt having longitudinal slot in the? threadedportion thereof; ot a nut having a transverse open ingi thereintemnnating' at its outer end in one face: of the nut; the-last mentionedfaceof said nut vary-ingrinsize from: the other faces thereof, -amemberinserted throughthe opening-of thenut to engage saidslot and securethenuaon the b'oltt and aplatepivot ally applied to the last-n'ientioned face of" (lopies ofrithis patentmam be obtained foffivecents -each by addressing-the Commissioner Garments;

said nut to conoealsa-id member and forum ing a face on the nutof equalsize to the otherfaees of said nut.

The combination with a bolt having a longitudinalslottherein; of a nuthaving a transverse opening therein terminating at its outer end in oneface of the nut, said ast mentioned face varying in size from the otherfaces of said nut, a member inserted through said opening toengage saidslot and secure the nut on the bolt, a plate forming' a completeface-for th'enu'tpivotally applied-to the last mentioned faceof said nutto coneeal the: membertherein; the face formed by sue-h plate A beingequal in size to the other faces of the nut and means to limit thepivotaPm'ovement of the-plate on the nut.
